The vehicle can get stuck in park or fail to engage, if the transmission is going bad. Low fluid levels can cause burning smells, leaks, and clunking, grinding or "humming" noises. Regular maintenance can extend the life of the tranny. Cost of a flush and filter change service for the Tracker averages $160-190 in materials and labor.
